New framework quantifies epistemic uncertainty in machine learning

Researchers have introduced a new framework for comparing and quantifying epistemic uncertainty in machine learning models. This framework, called the integral imprecise probability metric (IIPM), generalizes classical integral probability metrics to a broader class of imprecise probability models. IIPM not only allows for comparisons between different imprecise probability models but also enables the quantification of epistemic uncertainty within a single model. A key application is the development of a new measure called Maximum Mean Imprecision (MMI), which has shown strong empirical performance in selective classification tasks, particularly when dealing with a large number of classes.
